All I could get when I got my new tikka 6.5 PRC was H-1000. Was lookin at Retumbo and the 4831 SSC as well, but unobtanium at the time. So I bought 3 lbs of the H-1000.
Right out of the gate, during my load development, my hand loads and the H-1000 impressed the chit outta me !!
Both my Tikka TAC & my Browning LR Max(bought a few months for a range plinker) loved the hotter end of the hand loads. Right near max @ 59.9 gr ! NO pressure signs for me in either rifle, other than a slightly flattened primer face !
I easily found loads for my Nosler BT 120 grainers, 129 LRAB's, and my Hornady 143's & 147 ELDX's ! My Browning shot all the "try" loads I had left over from my Tikka with amazing results ! Liked the final loads as well. Not a lot of development done for it...no need to.
Unfortunately, health issues forced me to sell my Browning..kept my Tikka cuz it was love at first shot, and it shot a bit tighter than my LR Max ! !
